& MER- COMBINED LOCK AND LATCH FOR VEHICLE-DOORS.

Specification of Letters Patent.

Patented April 21, 1908.

To all whom it may concern:

Be it known that I, FRANK P; PFLEGHAR,

a citizen of the United States, residing at New Haven, in thecounty of New Haven and State of Connecticut, have invented a new and useful Improvement in aCornbined Lock and Latch for Vehicle-Doors; and I do hereby declare the following, when taken in connection with the accompanying drawings and the figures of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1 an inside view of a combined lock and latch for vehicle doors constructed in accordance with my invention, a portion of the ca plate being broken away, the locking bo t being shown in. the retired position. Fig. 2 a similar view showing the parts when the door is closed and the locking bolt thrown. Fig. 3 a sectional view on line ab of Fig. 1. Fig. 4 a sectional view on line c-d of Fig. 1. r I

This invention relates to an improvement in combined lock and latch for vehicle doors, and particularly for motor vehicle doors where it is desired to not only latch but look the door. In the usual arrangement of latches and locks of this character the latch is o erated on the inside of the door by a vertica y arranged lever that moves back and forth to disengage the latch, while the lock mechanism is turned by a handle arranged on opposite. sides of the door so that the lock may be opened from eitherthe inside or the outside.

The object of this invention is to avoid the necessit of a separate handle for the lock mechanism inside the door, and to provide means for operating both the look and the latch from a single lever; and the invention consists in the construction hereinafter described and particularly recited in the claims.

In illustrating my invention I have shown a lock of usual construction adapted to be applied to a vehicle door and comprising a p ate 2 having an outwardl turned flange 3 through which a latch bolt 4 extends the bolt being provided with a rearwardly extendin tail 5 having a finger 6 which is engaged y an o erating lever handle 7 which is pivoted to t e plate 2 near its lower edge, and extends upward through the top of the door where it is provided with a suitable handle for operation, the bolt being normally thrown outward by the usual spring 24. Below the latch is a rotatable lock bolt 8 having a hub 9 which receives a square spindle 10 of an operating handle, not shown, but which is arranged on the outside of the door, the bolt 8 when thrown passing through t e flange '3 so ,as to engage with a striking p ate 11 in' the usual manner. cam shaped and co-acts with a downwardly extending arm 19 on the latch bolt 4 so that turning the handle on the outside of the door will retire the latch bolt.

Above the latch bolt is a safety slide 12 having a downwardly extending arm 13 with a finger 14 adapted to project into the ath of a shoulder 15 on the hub 9 of the loo in bolt. This safety slide 12 is normally held in its outward position by a spiral spring 16 and is adapted to be retired by a lug 17 on the strike plate 11. When in its outward position the finger 14 stands in the path of the shoulder 15 on the locking bolt and cannot be thrown when the door is open; but when the door is closed the lug 17 forces the safety slide rearward so that its finger 14 is out of the path of the shoulder 15 permitting the door to be turned to its locked position. The arts thus described are of substantially usuaIoons'truction and held in place by a cap bolt 18. To open the door the locking bolt must be thrown back and then the latch bolt retired, and in the usual manner a handle must be provided on the inner end of the spindle 10 so that it can be turned from the inside or else it is necessary to reachoutside to first throw the locking bolt. To avoid this difficulty I attach a plate 23 to the hub 9 and ivot a link 20 thereto, which link is coup ed to the operating lever 7, the link having a clearance slot 21 through which a connecting screw 22 passes so that the o erating lever 7 may be moved inde endent y of the link 20 to operate the latci bolt when the locking bolt is in its retired position.

When the locking bolt is thrown to its locked position, as shown in Fig. 2 of the drawings, it moves the link 20 so that the outer end of the slot is in close engagement with the screw 22. When it is deslred to open the door from the inside after it has been looked as described, it is only necessary to remove the operating lever 7 rearward which movement rocks the hub'9 so as to retire the locking bolt at the same time the le- The hub is ver engages with the inner end of the latch bolt in the usual manner so that the latch is also retired. Thus by a single operation of the operating lever 7 the door is not only unlocked, but also unlatched so that it can be opened, both operations being performed by a single movement of the operating lever 7. While for convenience I have shown my inventionas applied to a combined lock and latch of one known form, it is apparent that it might be applied to other forms of combined locks and latches for vehicle doors.

I claim 1. In a combined lock and latch for vehicle doors, the combination with the locking bolt and a latch, an operating lever in engagement with said latch, and connections between the locking bolt and the operating lever, substantially as described. I

2. In a combined lock and latch for vehicle doors, the combination with the latch bolt and locking bolt, of an operating lever 1n engagement with said latch, and a link pivotally connected with said locking bolt and connected with said operating lever, substantially as described. I

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
